This is normally one of two things. If switch has failed then when you turn them on they will not come on. However, if the courtesy lamps are not coming on when you open the door then the BCM is probably the issue. It needs to see the input from one of the door sensors to turn them on and if it doesn't then the BCM needs replaced.
I included all the info on this. When the lights are turned on let's just check power from the BCM on one of the circuits and go from there.
